I'm using a WP-40 and 25 controlled by the Reef Angel in Anti-Sync.There is custom code in my INO that lnevo created for paultruner911 and helped me incorporate into my code to randomly change the mode of the DC pump every day or on reboot of the controller.

Sure did. I swear , this is a addiction . Now all ive got to get is the two other drivers and ill be set. Sounds like we will be running a similar setup maybe, maybe we can help each other with the codes

So I did more testing Sunday with the other header on the power supply with 12v, gnd, and dim but had no success getting it to do anything via pwm. I traced out some things on the driver board and there are some un-populated components along the path so I believe this is why it won't work. I'm going to just use an i2c dual channel digital potentiometer to do the dimming.
